Preliminary study on saltwater distribution of lowland area at West Coast, Johor Malaysia

Abstract Saltwater intrusion is a severe concern in coastal locations that pose threat to the groundwater environment. Climate change, tidal effects, and exploitation all have potential disrupt balance of salt water fresh aquifers which result seawater included studies area. The sea-level rise regarded as cause can enhance saltwater interface inland migration. Therefore, purpose this study assess zone mapping through open channel distribution. This qualified for monitoring around West Johor approximately 10 km especially Batu Pahat, such Parit Botak, Hailam Laut, Kampung Bahru Sri Pantai, Sungai Senggarang. salinity parameter was measured by refractometer instruments percentage units (ppt) PSU units. high low tides data collection on-site monitored analyzed distributed into using ArcGis 10.8 software. As result, Pantai highest saline test 3 4 tides. However, obtained from display maps monitor value contribution community be maintaining ecosystem existing structures gates bunds clean resources communities irrigation purposes.
